Hello,

It is my goal to add all 124 sub-briks from a dataset into one grand-sum 3D file. Is there a more efficient way to do this than 3dcalc -a data[0] -b data[1]... ? Is there some way to specify the n that I want to divide by for 3dmean? As of right now it automatically assumes the divisor to be 124 obviously. Any ideas?? If not, I've never used 3dcalc beyond -z, once it loops back around does it become -aa, -ab ..?

Additionally, I tried 3dMean -sum, but this does not work as it adds together all the input datasets, not the sub-briks within a dataset, so the output for me (for one dataset) is the same as the input.

Thanks!
Mikey
